Can indicators of myocardial damage predict carbon monoxide poisoning outcomes?
BMC Emergency Medicine, 2021 Background Carbon monoxide causes electrical, functional, and morphological changes in the heart. It is unclear, however, whether the indicators of myocardial damage can predict the patient’s prognosis after carbon monoxide poisoning.

The Impact of Positive and Negative Affect on QT Dispersion in Healthy Young Adult Men
Psychiatry and Clinical Psychopharmacology, 2021 Objective: In this study, we aimed to determine whether QT dispersion known to be associated with development of coronary artery disease is related with positive (PA) and negative affect (NA) in healthy young adult men.

Effect of isolated coronary artery ectasia on dispersion of P-wave and QT interval
The Egyptian Heart Journal, 2012 Background: Coronary artery ectasia (CAE) is well-recognized, angiographic finding of abnormal coronary artery dilatation, and detected in 0.3–5.3% of angiographic studies.

ARRITMIAS VENTRICULARES Y NUEVO SÍNDROME CORONARIO AGUDO EN PACIENTES CON INFARTO Y DISPERSIÓN DEL INTERVALO QT PROLONGADO / Ventricular arrhythmias and new acute coronary syndrome in patients with infarction and prolonged QT dispersion [PDF]
CorSalud, 2013 Resumen Introducción y objetivos: La isquemia miocárdica aumenta la dispersión del intervalo QT del electrocardiograma, ya que en estas circunstancias la duración del potencial de acción disminuye en la zona del insulto isquémico, al crear una dispersión

Faraday rotation: effect of magnetic field reversals
, 2010 The standard formula for the rotation measure, RM, which determines the position angle, $\psi={\rm RM}\lambda^2$, due to Faraday rotation, includes contributions only from the portions of the ray path where the natural modes of the plasma are circularly ...

Effect of remifentanil on QT dispersion
Korean Journal of Anesthesiology, 2009 QT dispersion (QT(d)) is an indirect measure of the heterogeneity of ventricular repolarization and can be used as a risk factor for complex ventricular arrhythmias. We measured the effect of remifentanil on QT(d) and heart-rate corrected QT dispersion (QT(cd)).Sixty ASA class I and II patients, who were between 20 and 60 years old, and who were ...
